One has to wonder why it took so long for Lexus to enter the hotly contested compact premium crossover market. The brand itself projects some 36,000 sales for its brand-new NX, which is set to go on sale in the US in November. Add that potential to the 100,000-plus RX crossovers it sells annually in the States and Lexus looks poised to put some hurt on German rivals like Audi, BMW and Mercedes.
